Comparative Review of the Most Important Weather Parameters and their Impact on Cotton Yield under Greek Conditions
Jul 31, 2018


Important weather parameters and their impact on cotton productivity were investigated in three main regions of Greek cotton production. Daily values of air temperature, solar radiation and precipitation for the period 1994-1997 were used, recorded on data loggers in fully automatic meteorological stations installed in the three study areas. The total global radiation data were transformed to sunshine duration in hours. Crop development was assessed with the accumulated heat units method above a threshold temperature (10oC). It was found that the year-to-year fluctuations in cotton productivity could be estimated with this method, but only at a given area with similar management practice. Additionally, sharp drops in temperature during critical stages of cotton growth may result in appreciable reduction in crop productivity, even if the actual air temperature does not fall below the threshold levels for cotton growth.
